Forums like this generally are dying, it’s mainly just us old people on them now as most youngsters are on things like Reddit or discord and obviously Instagram perhaps also Facebook (but that’s apparently also for old people)
I’ve seen a few online communities also go through a similar journey over the years, firstly they’re a (usually) friendly place where like minded people gather over a shared interest, then there’s a push to get numbers up before a sale to the big organisation who come in with all their rules and whatnot. Now they’re all suffering with the initial theme of the forum diluted, no real community feel and no new enthusiasm to power the whole thing. They basically become victims of their own success to a certain extent.
They often go from being communities and sources of information for the users to a way of getting sales or clicks on another business for the new owners and the users are just an inconvenience needing to be moderated.
Plus there’s not much flying going on with the pandemic and Microsoft flightsim 2020 is out, so many pilots are probably on that instead.
